Abstract

In a starting control valve assembly, starter valves 28 having tuning screws 31 capable of respectively adjusting the flow amount of air supplied to the intake port of each throttle body are arranged in a line in a valve body 22. Due to the provision of the valve body 22, a joint pipe 26, for supplying air having a flow amount adjusted using the starter valves 28, and throttle bodies are connected through a bypass tube, and the valve body 22 is separated from the throttle bodies.
This is to simplify idle opening amount between each cylinder and simplify the structure of a throttle body.
